25 Claims.

Our invention relates to a carrier for a railway car coupler and moreparticularly to a carrier for a coupler of the tight lock type. Ourinvention comprehends such a coupler carrier which is slidably mountedon a support beam and which affords a resilient and slidable support fora tight lock car coupler.

As coupled tight lock couplers have no provision for contour anglingvertically-or horizontally, the coupler heads must be allowed muchgreater side motion with respect to the car than is allowed previousdesigns of couplers. This hecessity for wide coupler anglingnecessitates anopening in the car end, the width of which depends to aconsiderable degree upon the typeof carrier device provided for supportof the coupler and arranged to slide on a support beam.

An object of our invention is to design a carrier such as abovedescribed which may be utilized with a beam of minimum length and whichis afforded a long bearing base on said beam. This objectis accomplishedby designing a carrier comprising bifurcated end portions adapted fortelescopic engagement with the upright end portions of the associatedsupport beam.

A further object of our invention is to design a carrier such as abovedescribed in which a carrier plate is afforded a three-point springsupport on an associated saddle member, said member bein afforded aslidable support as above described and said carrier plate being adaptedto support the shank of an associated coupler.

Another object of our invention is to provide a carrier plate havingtapered bearing surfaces on the bottom thereof so that when thesupported coupler is angled downward to bring the carrier plate incontact with the top of the supporting saddle member, the top portion ofthe plate may remain in full contact with the coupler and the under sideof the plate may be provided a full bearing across the top of thesaddle, thus per-. mitting equal distribution of pressure and evenstress on the supporting beam.

The A. A. R. specification for the construction of any passenger carsstates in Section J that A coupler carrier and its connections to thecar structure shall be designed to resist a vertical downward thrustfrom the coupler shank of 100,000 pounds for any horizontal position ofthe coupler, Without exceeding the yield points of the materials used.In view of this specificationit will be-readily apparent that the abovedescribed means for even loading of the beam is a very important featureof our invention.

; A further'objectof our invention is to provide pler carrier, thesupporting beam and the sup means retaining the saddle member inengagement with the supporting beam, said means comprising guide blocksrecessed in the inner surface of the front and rear walls of said memberand underlying the guide flanges of said beam, said blocks beingretained by means of bolt and nut assemblies received within slots inthe ends of said walls.

Intermediate its ends the wall 6 comprises ahorizontal cup-like ledge 94 affording a spring seat 96 with a hollowspring positioning, lug 98 thereon, the ledge 34 being reinforced by thevertical webs I00, I00. The rear wall 6 may comprise the depending lugI02 reinforced by the horizontal gusset I04 and affording a support fora train line support bracket fragmentarily indicated at I06 (Figures 1,2 and 14).

The carrier plate generally designated I08 shown in detail in Figures 9to 13 inclusive, comprises a central plate portion IIB flanged at thefront and rear thereof as at I20 and I22. The plate portion II8comprises at one end thereof a bifurcated portion or jaw I24 defined bythe front and rear legs I26 and I28 and at the opposite end thereof theplate portion II8 comprises a bifurcated portion or jaw I30 defined bythe front and rear legs I32 and I34. The rear leg I28 comprises theupstanding lug I36 adapted to about the lug 88 on the saddle member tolimit upward movement of the carrier plate with respect thereto and toabut the lug 90 on the saddle member to limit transverse movement of thecarrier plate with respect thereto. The front leg I20 comprises theupstanding lug I38 adapted to abut the lugs 56 and 58 on the saddlemember to limit upward and transverse movement of the carrier plate withrespect thereto, and the leg I26 also comprises the horizontal flangeI40 reinforced by the web I42, said flange I40 affording a spring seatI44 on the bottom thereof, said seat comprising the spring positioninglug I46.

The rear leg I34 on the carrier plate comprises the upstanding lug I48adapted to abut the lug 16 and the block I50 (Figures 2 and 4)positioned in the groove 14 and secured by the rivet I52, said block I50limiting upward movement of the carrier plate with respect to the saddlemember. The front leg I32 comprises the upstanding lug I54 adapted toabut the lug 32 and block I56 received in the groove 30 and secured tothe wall 22 on the saddle member by means of the rivet I 58, said lugI54 serving a purpose similar to that described for the lugs I36, I38and I48. The front leg I32 also comprises the horizontal flange I60affording a spring seat I62 on the bottom thereof, said seat including.the spring positioning lug I64 and being reinforced by the web I66.

It will be apparent that the legs I26, I 28, I32 and I34 guidably engagethe respective guide surfaces 54, 86, 26 and 10 on the saddle member andare held in assembled relationship therewith as above described.

Intermediate its ends, the rear portion of the plate member II8 of thecarrier plate is extended in a horizontal flange I68 and the reardepending flange I22 is continuous around the rear edge of the flangeI68 to define therewith a spring seat. I10 comprising the dependinghollow spring positioning lug I12, and the flange I68 is reinforced bythe spaced vertical webs I14, I 14. Tapered bearing surfaces I16, I16,as best seen in Figures 11, 12 and 13, are provided on the bottom of theplate member II8 of the carrier plate. It may be noted that the jaw I30at one end of the carrier plate is somewhat wider than the jaw I24 atthe opposite end thereof in order that the jaw I30 may be slipped overthe lugs 28 and 12 on the saddle member during assembly of the carrier.

The saddle member 2 and the carrier plate I08 are shown in assembledrelationship and in application to a supporting beam and supportedcoupler shank in Figures 2 to 4 inclusive Wherein it may be seen that acoil spring I18 is seated at opposite ends thereof on the spring seats59 and I44 and is positioned by the lugs 6I and I46 on said seats. Asimilar coil spring I is seated at opposite ends thereof on the springseats 38 and I62 and. is positioned by the lugs 42 and I64 on said seatsand a relatively large coil spring I82 is seated at opposite endsthereof on the spring seats 96 and I18 and is positioned by the lugs 98and H2 on said seats, said coil springs I18, I88 and I82 beingprecompressed and urgingthe carrier plate upward so that the lugs I86and I38 on the carrier plate are in engagement with the lugs 88 and 56on the saddle member and said springs are also operative to urge thelugs I48 and I54 on the carrier plate into engagement with the blocksI58 and I56 secured to the saddle member as heretofore described. Thusit will be seen that our invention comprehends an arrangement whereinthe carrier plate is afforded a three-point spring support from thesaddle member, whereby said carrier plate is enabled to follow allangular and torsional movements of the supported coupler, saidthree-point support comprising the front coil springs I18 and I88 andthe relatively large coil spring I82, said springs being supported fromrespective spring seats on the saddle member at the lower ends thereofand being engaged at the upper ends thereof with respect of springpositioning means on the carrier plate. The bottom surface of the topwall 4 of the saddle member is seated as at I84 on the top of thesupport beam I86 as best seen in Figures 3 and 4.. It may be noted thatthe beam I86 is of I-section and comprises the vertical web I88 and thetop and bottom horizontal webs I98 and I92, said top web I98 beingflanged at Opposite sides thereof as at I94, I94 (Figures 2, 3 and 14).The saddle member is retained in engagement with said beam by means ofguide blocks I 96, I96 positioned in the grooves 52, 52 and retained bybolt andnut assemblies I98, I98, said assemblies being slipped into theslots 44, 44 and retained therein by engagement of the washers 288, 288with the arcuate surfaces 48, 48 on the lugs 46, 46 positioned above andbelowthe slots 44, 44' as may be clearly seen in Figure 1. The saddlemember is also-retained with respect to the beam I86 by guide blocks282, 282 similar to the blocks I96, I96 and positioned in the recesses84, 84, said blocks being retained by the bolt and nut assemblies 284,284 received in the slots 88, 88 and retained therein by the washers286', 286 engaged with the arcuate surfaces on the lugs 82, 82 in amanner similar to the engagement of the washers 288, 288 with thearcuate surfaces on the lugs 46, 46. Further securing means is affordedby the L-shaped tie bar 288 secured as at 2I8, 2I8 to the depending lugs58 and I82 on the saddle member 2, said tie bar underlying the beam I66as may be clearly seen in Figures 1, 3 and 4. A coupler shank 2I2 isseated as at 2I4 on the top of the plate portion II8 of the carrierplate I88.

Figure 3 and the left half of Figure 1 show the coupler shank 2I2 in aposition of extreme vertical angling in which th carrier plate is urgeddownwardly so that the tapered bearing surfaces I16, I16 abut the topwall 4 of the saddle member 2. It will be apparent that by means of thetapered surfaces I16, I16 pressure will be evenly transmitted to thebeam I86 during extreme vertical angling of the coupler.

A Figure 14 shows a plan view of my novel coupler carrier with a couplerapplied thereto, said coupler having a head generally designated 2I6 andthe before-mentioned shank 2I2 adapted to be pivotally connected as at2I8 to a yoke member (not shown), and in this figure it maybe clearlyseen that the beam I88 comprises upstanding end portions 228,228 shownin sectional view. At the top of Figure 14 is shown in .phantom linesthe position assumed by my novel coupler carrier during extremehorizontal angling of the supported coupler and it may be seen that theshank 2I2 of the coupler abuts the wall I2 of the saddle member so thatsaid member slides along the beam I86 as the coupler angles horizontallyand that the jaw 24 of the saddle member receives therewithin theassociated upstanding end portion 228 of the beam I86 so that theupstanding wall I2 of the saddle member abuts said end portion as at 222in order to limit horizontal angling of the coupler. It will be readilyunderstood that the jaw I8 of the saddle memberis similarly adapted toengage the associated end portion 228 of the beam I86 in the event thatthe coupler angles in the opposite direction from the position indicatedin phantom lines at the top of Figure 14. Also, it may be noted thatbrackets 224, 224 are secured to the ends of the beam I86, I86 andfurnish support for an operating rod 226 secured as at 228 to saidbrackets, said bar underlying the shank 2I2 of the coupler,

'It is to be understood that we do not wish to be limited by the exactembodiment of the device shown which is merely by way of illustrationand not limitation as various and other forms of the device will, ofcourse, be apparent to those skilled in the art without departing fromthe spirit of the invention or the scope of the claims.
